ALFRED WARD, 0F BOWBELLS, NORTH DAKOTAl;

STUBBLE-BURNER.

Specification of Letters Patent.

Application filed May 15, 1914. Serial No. 838,729.

Patented Sept. 29, 1914.

To all whom it may concern:

Be it known that I, ALFRED WARD, a sub ject of the King of Great Britain, and a resident of Bowbells, in the county of Burke and State of North Dakota, have invented a new and Improved Stubble-Burner, of which the following is a full, clear, and exact description.

My invention has for its object to provide a stubble burner which may be conveniently moved to a position over the stubble which is to be burned, the frame of the burner carrying an apron at one end and shoes at its side for confining the fire under the top of the burner. The apron and shoes are adjustable to permit of their being raised when the burner is moved over a field and means are provided for spraying oil under the top of the burner, the oil being carried by a tank on the frame.

Additional objects of the invention will appear in the following specification in which the preferred form of my invention is disclosed.

In the drawings similar reference characters refer to similar parts in all the views in which Figure 1 is a plan view showing my stubble burner; Fig. 2 is a longitudinal sectional view of Fig. 1; and Fig. 3 is a sectional view on the line 33 of Fig. 2.

By referring to the drawings itwill be seen that a frame 5 is provided, a horizontal plate 6 being disposed over this frame 5 having depending flanges 7 at its sides. These 12. Extending down from the frame 5 there are plates 13 having bearings in which an axle 14 is journaled, this axle extending through the vertical slots 15 of the shoes 9, the wheels 16 being disposed at the outer sides of the shoes 9 and being mounted on the said axle 14. Pivoted to the frame 5 at 17 there is an apron 18 which extends downwardly and away from the axle 14, this apron 18 normally resting on an upwardly extending flange 19 on an apron 20, the apron 20 being mounted on the axle 14. Mounted at each side of the plate 6 there is a standard 21,'a lever 22 being fulcrurned at 23 to each of these standards 21. To the arm 24 of each of the levers thereis articulated at 25 an arm 26, each of the said arms 26 being secured to one of the shoes 9. It will, therefore, be seen that the shoes may be raised when desired by a downward movement of thearm 27 of thelever. Standards 28 are secured to the frame and extend upwardly therefrom, these standards 28 havis supported by the wheels 16, the other end of the frame being supported by the wheel or casters .26. Mounted on a frame 37 and disposed above the plate 6. there is a hydrocarbon reservoir 38, this hydro carbon reservoir 38 havingan outlet 39 commandedby a valve 40, the outlet 39 leading to the transverse pipe 41 to which is connected the spray tubes 42, these spray tubes42 being bent in the general direction of'the apron 18. A

hydro-carbon may be fed by these spray tubes 42 to the stubble below the plate 6 and within the shoes 9xandwh'en this hydrocarbon is lighted it will setfire to the stubble, the flames passing to the smoke stack or outlet 43 which extendsupward from an opening44 in the plate 6. As the flanges pass forwardly and upwardly through the smoke stack they are prevented from setting fire to the stubble beyond the stubble burner by the aprons 18 and 20. The stubble burner may be moved over a field bydraft animals hitched to the equalizer 45 connected with the frame by the pole 46, it being possible to raise the aprons and the shoes in the manner which has been described to prevent the aprons and shoes from hitting obstructions and hindering the movement of the stubble burner. The plates 10 of the shoes 9 have upwardly extending ends 10 the inner ends 10 being disposed in slots 6* in the plate 6.

Having thus described my invention I claim as new and desire to secure by Letters Patent:

1. In a device of the class described, a-

frame having a horizontal plate, an axle secured at one end of the frame, depending shoes at each side of the plate and movable vertically relatively to the frame, the shoes each having a vertical slot through which the axle is disposed, wheels mounted on the axle, means for raising the shoes relatively to the plate, an apron at one end of the frame depending from the plate.

2.1n a device of the class described, a frame having a horizontal plate, an axle secured at one end of the frame, a shoe at each side of the plate, each of the shoes hav ing a vertical slot through which the axle is disposed and a longitudinal slot extendingthrough the top of the shoes and a flange de pending at each side of the plate, the flanges extending into the slots in the shoes.

3. In a device of the class described, a frame having a horizontal plate, an axle secured at one end of the frame, a shoe at each side of'the plate, each of the shoes having a vertical slot through which the axleis disposed and a longitudinal slot ex tending through the top of the shoes, a flange depending at each side of the plate, the flanges extending into the slots in the shoes, levers fulcrumed at the top of the frame and means onnecting the arms of the levers with the shoes.

4. In a device of the class described, a frame having a horizontal plate disposed above the ground, shoes depending at the sidesof the plate, an apron pivoted at one end of the plate and extending therefrom downward and in the direction of the other end of the plate, a second apron pivoted between the first apron and the first mentioned end of the plate, the bottom of the second apron normally engaging the bottom of the first apron, and means for moving the second mentioned apron upward and in the direction of the-second mentioned end of the plate, there being an outlet in the plate adjacent the first apron.

In a device of the class described, a frame having a horizontal plate disposed above the ground, shoes depending at the sides of the plate, an apron pivoted at one end of the plate and extending therefrom downward and in the direction of the other end of the plate, a second apron pivoted be tween the first apron and the first mentioned end of the plate, the bottom of the second apron normally engaging the bottom of the first apron, means for moving the second mentioned apron upward and in the direction of the second mentioned end of the plate, there being an outlet in the plate adjacent the first apron, an axle secured at one end of the frame, a depending shoe at each side of the plate, the shoes each having a vertical slot through which the axle disposed, and means for raising the shoes relatively to the plate.

6. In a dev' to of the class described, a

frame having a horizontal plate, plates extending down from the frame and having bearings, an axle journaled in the hearings. flanges extending; down from the sides of the plate, two shoes, each having a longitudinal slot in which one of the iiangcs is disposed, the shoes also having vertical. slots through which the axle is disposed, means for raising the shoes relatively to the ilai'iges, and wheels disposed at the outer sides of the shoes and mounted on the axle.

7. In a device of the class described, a frame having a horizontal plate, plates extending down from the frame and having bearings, an axle journaled in the bearings, flanges extending down from the sides of the plate, two shoes, each having a longitudinal slot in which one of the flanges is dis.- posed, the shoes also having vertical slots through which the axle is disposed, means for raising the shoes relatively to the flanges, wheels disposed at the outer sides of the shoes and mounted on the axle, an apron pivoted to the horizontal plate adjacent the axle. a second apron pivoted to the axle, the bottom of the second apron normally ongaging the bottom of the first apron, and means for moving the second mentioned a pron r arw ardly.

In testimony whereof I have signed my name to this specification in the presence of the two subscribing witnesses.
